OPERATION & MAINTENANCE
USING THE DEPTH STOP
This Mini Milling/Drilling Machine comes with a depth stop which limits the
distance the head can travel while down feeding. The depth stop is mainly used
when repeat drilling to specific depth is required. To adjust depth stop:
1. Loosen depth stop lock handle (A) Fig.16.
2. With the cutting tool installed in the chuck, lower the head until the bottom of
the cutting tool reaches the desired depth of cut. Lock the head in this position
using the head locking lock handle (B).
3. Raise the depth stop (C) up against the head and retighten lock handle (A).
MAINTENANCE
WARNING!
FOR YOUR OWN SAFETY, TURN MACHINE OFF AND REMOVE
THE PLUG FROM THE POWER SOURCE BEFORE PERFORMING
MAINTENANCE, CLEANING OR LUBRICATION WORK.
This Mini Milling/Drilling Machine must be kept clean and greased/lubricated
regularly. Here are some basic rules for maintaining your machine.
1. Remove all chips from the machine before leaving machine. Always use work
gloves to remove metal chips.
2. A coat of automotive wax applied to the milling table will help keep the surface
clean and prevent rust.
3. Regularly inspect worm gears, leadscrews, power cord, loose hex. nuts or
bolts. Periodic lubrication of spring loaded handles and threaded parts will
make these parts easier to operate. Apply light grease every month to
leadscrews and column gear rack.
REPLACING MOTOR bRUSHES
This Mini Milling/Drilling Machine comes with a DC motor which has carbon
brushes. The carbon brushes eventually need to be replaced. To replace carbon
brushes:
1. Unscrew carbon brush cap (A) Fig.17.
2. Remove the carbon brush assembly (B) and replace it with a new one.
3. Repeat steps 1-2 for the second carbon brush on the opposite side of the
motor.
ADJUSTING GIbS
After hours of usage, the movement of the milling table and the head over the
slide ways will cause normal wear and play, and may need to be adjusted. To
adjust gib screws to eliminate gib play:
1. To adjust the X-axis gib, loosen 4 hex. nuts (A) Fig.18. Move the table in the
X-axis and tighten all 4 set screws (B). When the set screws are correctly
adjusted you will feel resistance. Once adjusted retighten hex. nuts (A).
2. To adjust the Y-axis gib, loosen 2 hex. nuts (C) Fig. 18. Move the table in the
Y-axis and tighten all 2 set screws (D). When the set screws are correctly
adjusted you will feel resistance. Once adjusted retighten hex. nuts (C).
3. To adjust the head gib, loosen 2 hex. nuts (E) Fig. 18. Raise and lower the
head and tighten all 2 set screws (F). When the set screws are correctly
adjusted you will feel resistance. Once adjusted retighten hex. nuts (E).
